Nice shot !

Here is a nice photo arrangement of AD in the garage, made by my brother Vincent.

End of the wind tunnel cession

Today was the last time of wind tunnel testing.

Some bugs in the coefficient have been detected, some post processing will be necessary before releasing official data. So that comparison will not be possible before some days.

Please be patient !

Some news from the Wind Tunnel

Here are some photos from the wind tunnel.

As the operating & recording system of S4 wind tunnel has jsut been updated, it is likely the release of the results will be delayed. Proper check of all the results will be necessary first.

Aerodynamic prediction worshop - End of prediction period

The Jibe 2 is entering the windtunnel this week. Today was riging period, tomorrow will be the first test with wind on.

Now the period for prediction has ended ! Here is a summary of the result i got, from 6 differnt people / team.

The excel file with more results.

Next part will be the comparison with the outcome of the test !

Here are some details about the methods used for those predictions.

	Method
MSch	Wing & tail + interaction : Miarex (Xfoil/lifting-line coupling, N=9 for wing, N=2 for tail) Fuselage : Xfoil + Mangler transformation Lateral : AVL + drag effect in aero axis (Miarex)
TPla	Xfoil plus 3D transpositions Simplified Cdi assumption Fuselage effect on Cm from in-house rule (from flight test & statistical approach)
ADe	XFLR5-V4
Jo&Stef	VSAERO : Linearized potential code, coupled with BL calculation
PLu	AVL for stability & induced drag Xfoil for airfoil drag with N<5>
FMe	XFLR5-V3
